S. A. BEERS, OF KINGS COUNTY, NEW YORK.

FASTENING RAILROAD-RAILS.

Specification of Letters Patent No. 20,248, dated May 18, 1858.

To all whom 'it may concern:

Be it known that I, SIDNEY A. BEERs, residing in the county of Kings and Stat-e of New York, have invented a new and useful improvement on the method of fastening down the coping-rail used in the plan of iron railway heretofore secured to me by Letters Patent dated October 27, 1857; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the aforesaid coping-rail, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a longitudinal elevation of a section of said railway. Letters a, a, is the coping rail; letters Z), b, is the foundation rail; letters c, c, is the head of bolts binding the coping rail to the foundation rail; d, d, is the top of the mortise, or slot, through which the bolt passes, elongated perpendicularly above the shank of the bolt; letter, e, is the elastic principle introduced between the foundation and coping rails; let-ter, f, is a niortise, or slot in the comb of the foundation rail elongated horizontally; and letter, g, is the joint in the coping rail.

Fig. 2, is a transverse section of the coping rail, and the upper portion of the foundation rail, on an enlarged scale; letter, a, is the coping rail; letter, b, is the elastic medium; letter, c, is the comb, and upper portion of the foundation rail; letter', d, is a bolt passing through a mortise, or slot in each side, or flange of the coping rail, elongated perpendicularly above the shank of the bolt, and through a mortise, or slot in the foundation rail elongated horizontally, by which arrangement the bolt is made to bind upon the bottom of the mortise in the coping rail, and upon the top of the mortise in the foundation rail, thereby preventing the coping rail from rising above the desired line; at the same time providing for a temporary compression of the elastic inedium on which the coping rail rests, and for any contraction, or expansion of the rails horizontally; without binding on the bolt.

I do not claim all the several parts, or devices as set forth and described in the accompanying specification and drawings, separately, but

What I do claim as my invention and desire to secure by Letters Patent is- The use of a bolt, or bolts, with nut, key, or clench, in combination with, or as an improvement on, the rail patented to me by Letters Patent dated October 27th, 1857, the bolt passing directly through both rails hori zontally; and also the form of the mortises separate or combined, for the object and purpose set forth in the above specification and claim and for no other purpose; as by reference to the accompanying drawings will more fully appear.

SIDNEY A. BEERS.
